Danger Overhead Cables Cone Sleeve for 750mm Traffic Cones

Who Is This For?

Electrical contractors, utility companies, highways maintenance teams, and construction site managers who already run a fleet of 750mm traffic cones and need replacement "Danger Overhead Cables" sleeves when existing sleeves degrade. Also relevant for any buyer who wants to convert a standard 750mm cone into a dedicated overhead cable warning cone without buying a complete new unit.

Typical Applications

• Replacement sleeve for the Mastercone 750mm Danger Overhead Cables cone when the original sleeve fades, cracks, or loses legibility
• Converting standard 750mm blue or orange cones into dedicated overhead cable warning cones for a specific scheme or site phase
• Stocking spare sleeves on long-duration utility and highway works where sleeve degradation is likely before the cone body fails
• Rail, telecoms, and power infrastructure works where overhead line equipment (OLE) or cable hazard warnings are required at access points
• Agricultural and rural construction sites where overhead cables cross access routes used by tall plant and machinery

How to Fit

1. Confirm the cone is a standard 750mm two-piece traffic cone. This sleeve is sized for 750mm cones only.
2. Slide the sleeve down over the top of the cone body from the apex. The pocketed design allows it to seat correctly over the cone taper.
3. The sleeve can be fitted directly over most existing reflective sleeves without removing the original. Check the fit is secure before deployment.
4. Confirm the "Danger Overhead Cables" text and lightning bolt symbol are fully visible and facing the direction of approaching operatives, drivers, and plant operators.
5. Inspect the sleeve at the start of each shift. Text and symbol must remain legible. Replace if faded, torn, or obscured.

Safety

• This sleeve is a hazard communication device. It does not make the area beneath overhead cables safe. All operatives must still follow the Electricity at Work Regulations 1989 and any site-specific electrical safety rules.
• A degraded or illegible sleeve does not fulfil its hazard warning function. Inspect before every shift and replace immediately if the warning text or symbol is not clearly readable.
• Do not use this sleeve as a substitute for a permit-to-work system, mechanical exclusion zone, or electrical isolation where those are required by the risk assessment.

Maintenance

Wipe with a damp cloth to remove mud, oil, or debris. The yellow background and black text must remain clean and legible at all times. Prismatic pocketed optics can be degraded by abrasive cleaning. Replace when the warning text or lightning bolt symbol is no longer clearly readable, when the sleeve is torn or split, or when the reflective performance has visibly degraded.
